EXECUTIVE SUMMARY

William van Wijngaarden has an impressive record of academic administrative leadership. This was particularly evident when he chaired the Faculty of Science and Engineering Council (2005-06) and York’s Senate (2010-13), and diplomatically diffused a number of contentious issues. He has been elected to several leadership positions in the International Union of Pure and Applied Physics (2002-08) and also held responsible positions in the American Physical Society and the Canadian Association of Physicists.

In 1999, Dr. van Wijngaarden led a successful application for a Network of Centres of Excellence serving as Program Leader of the Canadian Institute for Photonic Innovations (1999-01). CIPI comprised 65 researchers, 25 universities as well as over 40 company and research center participants. The researchers represented a variety of disciplines including biomedicine, chemistry, computer science, engineering and physics. Dr. van Wijngaarden managed a budget of over $22 million. In 2001, he chaired the Steering Committee on General Physics, which successfully recommended new initiatives for funding to the NSERC Reallocations Committee. He served multiple terms on the Appraisal Panel for the Ontario Council of Universities (2002-07) that approved over 300 graduate programs and served on the NSERC Physics Grant Selection (2007-09 and Research Tools & Instrument Committees (2015).

Dr. van Wijngaarden began research at the University of Windsor studying the electron impact

excitation of SO2. He graduated in 1982 with a BSc in Computer Science and a separate Honours BSc in Physics. He went to Princeton University and obtained a MSc in 1984 followed by a PhD in Physics in 1986.

After a year at Yale University as a research associate, Dr. van Wijngaarden joined the faculty at York University in 1988. In 2003, his research group laser cooled Rb atoms to create Canada’s first Bose Einstein Condensate. More recently, he measured the relative nuclear charge radius of 6,7Li with an uncertainty of about 1 x 10-18 meter. He has also studied applied/interdisciplinary topics such as laser isotope separation, electromagnetically induced transparency for use in optical switching, environmental monitoring of pollutants and climate change. He has more than 80 refereed publications and given over 300 conference presentations and invited seminars.

Dr. van Wijngaarden has taught over a dozen different courses to thousands of undergraduate and graduate students. He is known for well organized lucid lectures. His pedagogical innovations have borne results. Typically, 90% of the students pass his challenging introductory physics course taught to nonphysics majors.

Dr. van Wijngaarden received the University of Windsor Board of Governor’s Medal in 1982, the 1967 NSERC graduate scholarship, Princeton University’s Joseph Henry Scholarship and a number of large research grants. He and his wife Theresa are the proud parents of Arie, Alice, Emma, Ellen and Marinus. He is conversant in Dutch and reads French and German.

EDUCATION

June 1986 Ph.D., Physics, Princeton University

W. A. van Wijngaarden developed a new method to measure oscillator strengths or absolute transition probabilities which was important for optimizing laser isotope separation. The thesis was entitled “The Inverse Hook Method for Measuring Oscillator Strengths”. The significance was that this innovative method was applicable to the study of transitions between excited states unlike existing techniques. This enabled the selection of transitions that maximized the efficiency of stepwise laser excitation to selectively ionize a particular isotope.

June 1984 M.Sc., Physics, Princeton University

A Preliminary Examination tested knowledge of Classical Mechanics, Electricity and Magnetism, Statistical Physics and Quantum Mechanics. The subsequent General Examination tested knowledge of General Relativity, Solid State Physics, High Energy Physics, Nuclear Physics and Atomic Physics. In addition, students were questioned by two separate committees. The final requirement was completion of an experimental project which was entitled “Relaxation of Spin Polarized Xe131 Nuclei”. This showed how the angular momentum of optically pumped Rb atoms could be transferred to align the Xenon nuclear spins which is today used for NMR imaging.

October, 1982 B.Sc., Computer Science, University of Windsor

This degree gave extensive experience developing software programs using a variety of computer languages including Assembler, Fortran, Basic and PL/One.

June 1982 Honours B.Sc., Physics, University of Windsor

W. A. van Wijngaarden was the top student of his graduating class and received the University of Windsor Board of Governor’s Medal. He also did an Experimental Project as a Senior Thesis entitled “Dissociative Excitation of SO2 by Controlled Electron Impact”.

June 1978 Forster Collegiate

W. A. van Wijngaarden was the top student of his graduating class and received the highest University of Windsor Entrance Scholarship. He graduated with 45 credits of which 11 were Grade 13 subjects, nearly twice the number required.


PROFESSIONAL AND ACADEMIC EXPERIENCE

2000–present Full Professor, Dept. of Physics & Astronomy, York University

Notable administrative responsibilities included chairing the Senate of York University, serving multiple terms on the Graduate Adjudication Committee of the Council of Ontario Universities, chairing the Faculty of Science and Engineering Council, holding various positions with the International Union of Pure and Applied Physics and leading the successful application to create the Canadian Institute of Photonic Innovations, a Network of Centres of Excellence. Significant research milestones included creating Canada’s first Bose Einstein Condensate, demonstrating an array of microtraps for ultracold atoms, precisely measuring lithium isotope shifts to determine the relative nuclear charge radius to an accuracy of a few parts times 10-18 meter as well as examination of climate change in North America during the last 60 years. Teaching innovations in first year Physics led to better understanding of the subject material and improved student retention. 2003-2004 Visiting Scientist, Environment Canada

Over a hundred million archival observations of temperature, humidity and precipitation were carefully examined to study human caused climate change. The data were first analyzed for inhomogeneities caused by changes in instruments and/or observation procedure. Trends were found for time series not having abrupt discontinuities. Statistically significant warming trends were most evident in the Canadian Prairies and the western Arctic in winter and to a lesser extent in spring corresponding to a decrease in relative humidity and precipitation. 1992-1999 Associate Professor, Dept. of Physics & Astronomy, York University

A major responsibility was serving in various capacities in the American Physical Society and the Canadian Association of Physicists. Dr. van Wijngaarden’s laboratory developed a novel technique to measure frequency intervals using a laser beam modulated using either an acousto or electro-optic modulator. This allowed the determination of hyperfine intervals, stark shifts and polarizabilities to unprecedented accuracies. The research also demonstrated electromagnetic induced transparency for use in optical switching. 1988-1992 Assistant Professor, Dept. of Physics & Astronomy, York University

A reputation for very clear and lucid lectures was developed in teaching Mathematics and Physics courses to undergraduate and graduate students. Dr. van Wijngaarden’s course notes were subsequently used by several colleagues. A research laboratory was established and the hyperfine interaction was studied using Quantum Beat and Level Crossing spectroscopy. 1987-1988 Research Associate, Dept. of Physics, Yale University

Dr. van Wijngaarden worked on an experiment to precisely measure the Rydberg constant and frequency intervals in Helium. 1987 Instructor, Dept. of Physics, Princeton University

Responsibilities included supervising teaching assistants in a first year physics course. A seminal paper on optical pumping was also published. 1986 Research Associate, Dept. of Physics, Princeton University

Publications resulting from the PhD work were submitted and a graduate student was supervised on a Quantum Beat Spectroscopy experiment.

NOTABLE ADMINISTRATIVE CONTRIBUTIONS

YORK UNIVERSITY SENATE VICE CHAIR/CHAIR (2010-2013)

Dr. van Wijngaarden chaired Senate meetings efficiently in a collegial manner and at times with humour. His leadership was noted for respectful listening to diverse views and patient consensus building to resolve a multitude of issues. His advice was sought on many informal occasions by the President and Provost, as well as formally when he led or was an active participant in the deliberations of the following committees.

1. SENATE EXECUTIVE (CHAIR): This committee which includes the President, Provost and members from each of York’s nine Faculties, met monthly to approve Senate agendas and receive reports from its SubCommittees and other Senate Committees.

a) EQUITY SUBCOMMITTEE (CHAIR): This committee, consisting of faculty as well as undergraduate and graduate students, investigated concerns arising from the Canadian Federation of Students Ontario Task Force on Campus Racism Report and a Graduate Student Association (GSA) Equity Audit that purported to show a disproportionate number of students of certain ethnic/racial backgrounds have been charged with academic dishonesty. It examined relevant documentation, interviewed over a dozen individuals in positions dealing with graduate students, and international students in particular, and received a presentation from GSA officials. Dr. van Wijngaarden authored the unanimous committee report that found no evidence to substantiate anecdotal concerns raised in the two reports. However, a number of the supports available to graduate students and faculty were found to be suboptimal and recommendations were made to improve Student Orientation and expand Writing Support services particularly geared to international students.

b) WORKING GROUP ON EXTERNAL PARTNERSHIPS (CHAIR): In the spring of 2012, York University underwent considerable acrimonious tumult about a proposed partnership with the Centre for International Governance Innovation (CIGI) funded by J. Balsillie, culminating in a petition signed by over 300 faculty members expressing strong concern about the potential adverse impact on academic freedom and the university’s autonomy. Dr. van Wijngaarden led a Working Group that consisted of a diverse array of 8 highly respected and experienced faculty members plus a graduate student. It discussed voluminous documentation from internal sources and other universities, a growing scholarly literature and media accounts as well as interviewed Organized Research Unit Directors, the President of the York University Faculty Association, all Faculty Deans and the Vice Presidents of Fund Raising & Development and Research & Innovation. Dr. van Wijngaarden together with the committee secretary R. Everett, authored the 29 page report that was unanimously endorsed by the Working Group. It recommended Senate endorse a list of 8 principles for External Partnerships that clearly and transparently spell out the responsibilities of the University and External Partners. The report was greeted with enthusiasm in an atmosphere very markedly more collegial than that existing on campus 12 months earlier.

2. BOARD OF GOVERNORS: In addition to attending these meetings held every 3 months, Dr. van Wijngaarden developed an excellent rapport with Board Chairs, Paul Cantor and Julia Foster as well as with other Board of Governors. He and the Board Chair led the annual meeting of the Executives of the Senate and Board of Governors. An issue of particular importance was the special joint meeting called to discuss the reappointment of the President.

3. ACADEMIC POLICY, PLANNING AND RESEARCH: This committee met on average every 2 weeks and worked with the Provost to formulate a University Academic Plan and subsequently hear annual reports given by each Dean. In conjunction with the Vice President of Research & Innovation, it also formulated a Strategic Research Plan, created a program for York Research Chairs to stimulate world


class research and revised procedures for creating/renewing Organized Research Units. A number of other issues were considered such as the university response to the Council of Ontario Universities initiative on Online Learning, University Promotion to high school students in Ontario as well as potential international students, Student Satisfaction, Tenure and Promotion Policies etc.

4. ACADEMIC STANDARDS, CURRICULUM AND PEDAGOGY: Each year, scores of new programs and curricular changes, recommended by this committee, are forwarded to Senate for approval. Some of these proposals were contentious and Dr. van Wijngaarden successively mediated several disputes.

5. HONOURARY DEGREES AND CEREMONIALS: This committee met several times each year to consider candidates who have made significant contributions to their community, York University, Canada and/or the world. Approved candidate names remain confidential and are entered into a pool, from which the ultimate selection is made by Chancellor Roy McMurtry and President Mamdouh Shoukri. Dr. van Wijngaarden was particularly satisfied to award an Honourary Doctorate at convocation to a distinguished individual he nominated.

6. PRESIDENT’S ADVISORY COUNCIL ON HUMAN RIGHTS: This high level group of university administrators met every 3 months to listen to faculty and student concerns about diversity issues and advise the President regarding concerns such as upholding Academic Freedom when contentious issues arise on campus, and how University policies may need to be adjusted to accommodate the recently passed Accessibility for Ontarians with Disabilities Act (AODA).

7. STUDENT ROUNDTABLE: This monthly meeting chaired by the Vice President of Students comprised student leaders from the various Colleges as well as representatives from the undergraduate York Federation of Students and the Graduate Students Association.

8. RECRUITMENT COUNCIL: This monthly meeting discussed York University’s ongoing promotion and recruitment efforts such as: the Ontario University Fair held at the Toronto Convention Center, university open house as well as entrance scholarships.

9. MISCELLANEOUS: This included a number of addresses to student groups and Faculty Councils and leading Spring and Fall convocations, sometimes in French. Dr. van Wijngaarden was also responsible for deciding whether to close the university due to inclement weather.

FACULTY OF SCIENCE & ENGINEERING COUNCIL CHAIR (2004-2006)

The Faculty of Science and Engineering (FSE) faced a number of unusually contentious issues during the Dr. van Wijngaarden’s tenure as Council Chair.

1. ENGINEERING: The three engineering programs in Geomatics, Space Science and Computer Engineering failed to be accredited. The Accreditation panel pointed out a number of deficiencies. At the request of FSE Dean Gill Wu, Dr. van Wijngaarden put together a proposal to create a School of Engineering to be housed in FSE. This proposal was initially greeted with considerable reservations. Dr. van Wijngaarden had extensive discussions with the chairs of the FSE departments and others. The result was the unanimous approval by FSE Council. Dr. van Wijngaarden subsequently presented the proposal to the Senate Executive Committee and it was approved by York’s Senate. The three engineering programs subsequently gained accreditation status.

2. TRANSFER OF SCIENCE AND TECHNOLOGIES STUDIES PROGRAM into FSE: Moving this program from the Faculty of Arts into FSE had been tried several years earlier and failed after considerable controversy. Dr. van Wijngaarden patiently listened to people’s concerns before bringing it to FSE Council, where it was passed unanimously.


3. TRANSFER OF MATHEMATICS DEPARTMENT into FSE: There was initial concern about

whether FSE would approve the transfer of Mathematics from the Faculty of Arts. Dr. van Wijngaarden suggested that the motion “welcoming the Mathematics Department into FSE” which Council passed unanimously.

4. EXECUTIVE AND PLANNING COMMITTEE: This committee which included the Dean and members from each Department, met monthly to approve FSE Council agendas. It received reports from various committees regarding curriculum, petitions, admissions, appeals, nominations etc. which were forwarded to Council.

5. DECANAL SEARCH: President Lorna Marsden contacted Dr. van Wijngaarden seeking advice about

the composition of the Decanal Search Committee following her decision not to reappoint the Dean of FSE.

CANADIAN INSTITUTE FOR PHOTONIC INNOVATIONS (1999-2001)

Dr. van Wijngaarden led the effort to establish the Canadian Institute for Photonic Innovations (CIPI), a Network of Centres of Excellence beginning in 1997. The competition consisted of two rounds. Initially, there were 72 applications of which 11 were shortlisted. Each of these was then given some seed money to prepare a detailed full proposal. Dr. van Wijngaarden led the CIPI delegation that underwent rigorous all day questioning by an Expert Panel consisting of leading photonics researchers from around the globe. Their report was submitted to NSERC which selected 3 Networks to fund in 1998. The head of NSERC, Dr. T. Brzustowski notified Dr. van Wijngaarden that CIPI was the very close runner-up and suggested he contact the government for additional funding. Dr. van Wijngaarden organized a successful lobby that briefed members of the inner Cabinet. CIPI was announced in 1999 and comprised 65 researchers, 25 universities as well as over 40 company and research center participants. The researchers represented a variety of disciplines including biomedicine, chemistry, computer science, engineering and physics. Dr. van Wijngaarden’s responsibilities included the following.

1. APPLICATION LEADER: a) UNIVERSITY RECRUITMENT: Dr. van Wijngaarden travelled to nearly every university in

Canada to recruit participants. A laboratory visit allowed a much better assessment of an individual’s research activity than reading a report or listening to a video teleconference call.

b) INDUSTRIAL AFFILIATE RECRUITMENT: Dr. van Wijngaarden visited private sector companies, hospitals and government research organizations to better understand how CIPI could help meet their research needs. The overwhelming feedback was to train more highly qualified personnel. Some researchers were concerned that their students would be seduced by high salaries in the private sector before completing their degrees. This occurred to H. Chen, a talented postdoc of Dr. van Wijngaarden, who was recruited along with his wife to work for EXFO, a Quebec City telecommunications company.

c) WORKSHOP ORGANIZATION: A workshop bringing together industrial and university participants, was held in Toronto to formulate project proposals.

d) PROPOSAL ASSEMBLY: The first volume described each of the 5 Theme areas: Nanotechnology for Photonics, Engineering of Photonic Devices, Photonics for Information Technology, Ultrafast Photonic Technology and Precision Photonic Measurements along with the specific 17 projects of these themes as well as the Network Administrative Structure, plans for Technology Exploitation, Training of Highly Qualified Personnel etc. The remaining volume contained CVs of the researchers.


2. PROGRAM LEADER: a) CREATION of BOARD of DIRECTORS: Dr. van Wijngaarden visited potential directors and

organized their first meeting. Other committees were also established and membership was proposed with due regard for principles such as affirmative action.

b) NETWORK AGREEMENT: Dr. van Wijngaarden wrote this legal document which governed all aspects of CIPI in close consultation with lawyers. This document had to be approved by 1) the university investigators, 2) CIPI’s Board of Directors, 3) a majority of the participating universities and finally 4) NSERC. Dr. van Wijngaarden adroitly handled the challenge of dealing with the so called “G-8” grouping of universities who believed their research credentials entitled them to special treatment.

c) HIRING OF ADMINISTRATIVE STAFF: This included hiring and overseeing the work of various personnel and a Network Manager. Dr. van Wijngaarden closely supervised the development of the website and promotional literature, progress reports, organization of annual meetings etc.

d) PHOTONICS SPEAKING TOUR: Dr. van Wijngaarden gave a talk entitled “Research and Career Opportunities in Photonics” to 16 universities. A CD of the talk sufficiently impressed the Hon. P. Manning, Leader of the Opposition, that he came to visit Dr. van Wijngaarden’s lab at York University.

3. FINANCIAL ACCOUNTABILITY: CIPI’s budget was over $22 million. Dr. van Wijngaarden was responsible for regular financial reports to NSERC and the Board of Directors to ensure proper allocation and expenditures of funds.

4. RESEARCH MANAGEMENT COMMITTEE (CHAIR): The research program was divided into 5 themes, each of which was directed by at Theme Leader who reported to Dr. van Wijngaarden. The Theme Leaders plus representatives of network investigators and research affiliates comprised the Research Management Committee. It solicited regular reports from each theme and project to monitor research progress. It also received research proposals and decided which to recommend to the Board of Directors for funding. Dr. van Wijngaarden oversaw special efforts to promote meritorious women and young researchers.

5. INTELLECTUAL PROPERTY: Dr. van Wijngaarden was involved in the transfer of technology that resulted in part by CIPI funding, to a startup company. He also gave a seminar about the responsibilities of network investigators regarding intellectual property. In addition, Dr. van Wijngaarden researched technology transfer of the various Networks of Centres of Excellence. His report, submitted to the Board of Directors, impressed Jean-Claude Gavrel, Director of the Networks of Centers of Excellence Program, who commented that this survey was something his organization should have undertaken.

ONTARIO PHOTONICS TECHNOLOGY INDUSTRY CLUSTER (OPTIC) (1999-2001)

Dr. van Wijngaarden was a founding Board member of OPTIC which is a community of high technology companies and organizations working to support the photonics industry in southern Ontario through:

1. Aiding the global marketing of photonics products

2. Enhancing communication

3. Facilitating strategic alliances and investments

4. Improving education in Optics and Photonics

5. Representing the interest of industry with economic development agencies

RESEARCH INTERESTS

PRECISION LASER SPECTROSCOPY

Dr. van Wijngaarden’s group invented a novel method to precisely measure frequency intervals. It uses a laser that is modulated using either an acousto-optic or electro-optic modulator. The frequency modulated laser beam then intersects an atomic beam. Fluorescence produced by the radiative decay of the excited atoms is detected as the laser frequency is scanned across the resonance. The resulting spectrum contains pairs of peaks separated by the modulation frequency which permits the laser frequency scan to be calibrated. The apparatus is far simpler and cheaper than using a Fabry Perot etalon to monitor the laser frequency and the results are more accurate. This technique has been used to determine Stark shifts and hyperfine splittings with accuracies up to parts in ten thousand. Most recently, our 6,7Li isotope shift measurements have permitted the determination of the relative nuclear radii with an accuracy of parts in 10-18 meter. This constitutes one of the world’s best microscopes.

ULTRACOLD ATOMS

Laser cooling and atom trapping is one of the truly hot research topics. Interesting physics such as Bose Einstein Condensation (BEC) was first proposed by S. Bose and A. Einstein in 1924 predicting that near absolute zero, bosons (particles with integral spin) would all occupy the same state. Experimental interest was limited because no one had any idea how to achieve such ultralow temperatures. It was not until the mid 1990s after novel methods to cool atoms using lasers and store them in magnetic traps had been developed, that BEC was first observed. Dr. van Wijngaarden’s group was the first in Canada to create a BEC which consisted of about 8 x 106 87Rb atoms cooled to a temperature of 75 nK. Since then, he and his students have demonstrated how to transfer ultracold atoms between optical and magnetic traps. Most recently, they demonstrated a linear array of microtraps fabricated using the same lithographic technique as used to make computer chips. Each microtrap consists of two concentric loops having oppositely oriented currents. The inner loop radius is only 300 microns. The ultracold atoms are trapped at a distance that can be precisely controlled from 300 to less than 50 microns above the so called atom chip surface. This novel trap can be replicated to create a two dimensional array of microtraps that may be of interest to study quantum information.

CLIMATE CHANGE STUDIES

There has been increasing concern in recent years about how humans are changing the Earth’s climate. Dr. van Wijngaarden worked with scientists at Environment Canada to analyze archival data of humidity, temperature and precipitation. It is important to first examine data for inhomogeneities which may arise from changes in instruments and/or observing procedure. Most recently, Dr. van Wijngaarden studied over ¼ billion hourly values of temperature and relative humidity observed at 309 stations located across North America during 1948-2010. Trends were found for data that did not exhibit abrupt discontinuities. Statistically significant warming trends affecting the Midwestern U.S., Canadian prairies and the western Arctic are evident in winter and to a lesser extent in spring while statistically significant increases in water vapor pressure occur primarily in summer for some stations in the eastern half of the U.S. The changes in water vapor were smaller than that found in other studies that examined far fewer data over a much shorter time span.

TEACHING

Dr. van Wijngaarden has taught over 100 one semester courses plus dozens of tutorials during his 25 years at York. He has taught at all undergraduate levels as well as to graduate students. A number of these courses have been given on unpaid overload. His teaching encompasses an incredible breadth of subjects including: Linear Algebra, Introductory Calculus, Introductory Physics, Electricity & Magnetism, Electrodynamics I, Electrodynamics II, Advanced Classical Mechanics, Modern Physics, Laser Electronics, Optics, Solid State Physics, Relativistic Quantum Mechanics, General Relativity and Atomic Physics.

PEDAGOGICAL TECHNIQUE

1. METICULOUS PREPARATION: A considerable time is spent to write immaculate lecture notes that read better than any textbook. Work is also done to create original interesting assignment problems. A number of colleagues (J. Burt, M. George, E. Hessels, R. McEachran, S. Jeffers) have used Dr. van Wijngaarden’s notes in their teaching.

2. VERY LUCID LECTURES: Dr. van Wijngaarden is known to explain things very clearly beginning from basic definitions. When something is difficult, he slows down. Questions are asked to ensure students grasp the material. The use of humour before introducing a particularly difficult concept also ensures the student’s undivided attention.

3. EFFECTIVE CLASSROOM MANAGEMENT: Students regularly comment that unlike most other classes, distractions due to chatting students, neighbouring students browsing inappropriate websites, cell phone use etc. do not occur in Dr. van Wijngaarden’s classes. A colleague entering a Phys 1410 lecture commented that students certainly were paying attention.

4. TEACHING/LAB ASSISTANTS: Graders receive assignment/quiz solutions along with a clear, straight forward grading scheme. Lab assistants are required to do each experiment themselves and show Dr. van Wijngaarden their writeup as though they were a student.

5. MOTIVATIONAL MARKING SCHEME: a) Weekly Assignments/Quizzes are marked and returned promptly usually by the next lecture. b) Posting Assignment/Quiz Solutions on Website. Dr. van Wijngaarden was one of the first at York to

make his own website to post solutions. c) Dropping Lowest Assignment/Quiz: This encourages students all is not lost because of one low mark. d) Substantial Final Exam: The final exam should be worth at least 40% of the course grade to help

students whose term mark is lower than desired. e) Final Mark Round Up: York University assigns letter grades i.e. A+ for a mark ≥90% etc. Dr. van

Wijngaarden tells each class that he is too cheap to replace his defective calculator that automatically rounds a mark of 89% to 90%, 79% to 80% etc. This avoids considerable frustration for students and enhances their confidence that they are fairly treated.

6. UNLIMITED OFFICE HOURS: Dr. van Wijngaarden’s office door is always open from early in the morning to late in the afternoon. The only criteria for getting help with a homework problem is a student must first show they have made a serious attempt to do it themselves.

7. GRADUATE COURSES: Enrollments are typically small and Dr. van Wijngaarden distributes the course lecture notes. Students are expected to read the notes before each lecture. This allows more material to be covered and special attention to be devoted to particularly challenging areas.

8. HIGH STANDARDS: Dr. van Wijngaarden encourages each student to maximize their potential. He tells the class: “There is no shame in getting a C if you have done your best. However, if you were lazy and get a B+ you should work harder.” Learning good work habits helps students throughout their career.

TEACHING EFFECTIVENESS Students have a very high regard for Dr. van Wijngaarden’s classroom organization and comment they learn far more in his courses than elsewhere. During the summer of 2013, a student in Phys 1410.06 said “I wish my McMaster professors taught like you”. Many instructors have informally sought his advice. In 2005, he was asked to give a seminar, “Insight into Teaching Physics” to the Physics and Astronomy graduate students. Several long time faculty members were also in attendance. In August, 2013, Dr. van Wijngaarden was asked to be a panel participant at the Orientation Workshop of new faculty members at York University. Vice Provost Pitt specifically asked him to mention his recent experience teaching introductory Physics to nonphysics majors. In May 2013, he began Phys 1410.06 with 150 students on the first day. Three months later, 140 passed the course and 1/3 received either an A or A+. It should be noted that in previous years the Phys 1410 exam was also given to 4th year Honours Physics students who performed miserably. This success rate is unheard of even when one takes into account an additional 10 students who dropped the course and were replaced by latecomers.

ANONYMOUS STUDENT EVALUATION COMMENTS

ACMS 1050/MATH 1505: Calculus for the Biological Sciences

Prof. van Wijngaarden is an excellent teacher. He was always on time and made himself available evenings, when tests were scheduled. The evaluation marks are very fair. Tests were all reflective of homework assignments. I’m pleased with the effort put into the course by Prof. van Wijngaarden.

Excellent, Dr. van Wijngaarden is an amazing lecturer. His notes are clear i.e. examples for everything he taught.

The professor was very responsive to all the questions, even though some were stupid (but he did not show that).

The lecturer was always available for extra, extra help outside the class hours and outside the designated tutorial hours. He was even available in the evening (7:00 – 10:00 pm).

PHYS 2020: Electricity and Magnetism

Dr. van Wijngaarden truly wants his students to do well and no matter what you know you’re E & M when you finish. Go for help if you need it. He is always available and pleasant.

Probably learned more in this course than in the rest of my courses put together. At the same time it was always fair. Gives people a chance to do well.

As far as I am concerned this was the best-taught course I have attended since I study at York. I believe that other teachers should learn from his teaching capabilities and adapt his methods. He made the material more interesting than it already was to me!

Fabulous teacher. Interesting course. Was able to provide an extra test to raise class average.

I think we should call up the head of Biology and get him/her to clone Dr. van Wijngaarden so that he can teach all the 2nd, 3rd and 4th year physics courses, and possibly some of the computer ones.


PHYS 3010: Classical Mechanics

I feel Dr. van Wijngaarden is an excellent prof with high standards we should all aim for and I think that I would like to have him again, as I learned a lot in his course. Thank you.

PHYS 3020: Electrodynamics I

Professor Wijngaarden is an excellent teacher with a good sense of humour. He is well versed in the subject matter and is able to pass it on in a clear and concise manner.

The professor (W. van Wijngaarden) was great! He would help the students at any time and wanted the students to do well, always.

Dr. van W. should teach all other professors how to organize and present their lectures.

PHYS 4020: Electrodynamics II

Just peachy, an excellent course.

Far exceeded expectations, terrific course and very good professor! Simply put, V.W. is one of the best Profs in the department.

PHYS 4050: Solid State Physics I think this course provided an excellent introduction into Solid State Physics. Dr. van Wijngaarden is an excellent lecturer who welcomes students with problems and enjoyed teaching the course (it showed!) The professor is very knowledgeable and shows enthusiasm for this course, which makes it more interesting. Structure of course is very nice, i.e. students are not note takers for an hour every day of class and thus, discussion on material is made possible. Just one more thing “Keep up the fine work Dr. van Wijngaarden”.

PHYS 4100/5110: Quantum Electronics Dr. van Wijngaarden is a very knowledgeable prof. The course was interesting and worthwhile. I think that more undergrads should be encouraged to take this course. I found it very interesting and have learned a lot. I agree with Dr. van Wijngaarden’s stressing of understanding the physics, not getting bogged down in the algebra.

PHYS 5000: Relativistic Quantum Mechanics This was a very good course in providing a fundamental knowledge of physics that grad students should know. It was nice to see theoretical complexity simplified by using a strong experimental theme.

PHYS 6060: Atomic Physics I anticipated a fast pace course as it turned out to be. I like the fact that little to no time was wasted on formulae and useless math.
